I will give you one example how Kṛṣṇa sometimes breaks His promise. It is very nice story. Kṛṣṇa, when He joined Arjuna, He promised from His own side that, "Because the fight is between your brothers, so it is not My duty . . . because both of you are My relatives, so it is not My duty to join one party and not to join another. But because I have divided Myself—Myself one side, and other side, My soldiers—but Duryodhana has decided to take My soldiers, not Me, so I shall join you. But I shall not fight. I shall not fight. I may take some work which may assist you." So Arjuna offered, "Whatever work You like, You can take." So He said: "All right. I shall drive your chariot."
So Kṛṣṇa's promise was that He will not fight. But at a time when Arjuna was perplexed by fighting with Bhīṣma . . . Bhīṣma was the greatest fighter, although he was very old man. Duryodhana incited him that, "Because the other side are your very pet grandsons, you are not fighting fully." That was the complaint of Duryodhana. So in order to encourage him, Duryodhana . . . Bhīṣma said to Duryodhana, "All right, tomorrow I shall finish all these five brothers. Tomorrow I shall finish. And I have got now special arrows for killing these five chivalrous brothers."
So Duryodhana was very intelligent. He told, "All right, please keep these five arrows with me for the night. I shall deliver you tomorrow in the morning." "All right, you take it." And Kṛṣṇa understood. Kṛṣṇa is, everything knows, past, present and future. Kṛṣṇa knew it that "Bhīṣma has now promised. He will kill." So He asked Arjuna—this is also politics—that, "You go to Duryodhana. Do you remember that Duryodhana"—Duryodhana is elderly than Arjuna—"that he would keep some promise which he has offered to you?" Duryodhana told him, "Arjuna, whenever you want something, I shall give you." "Now this is the time. You can go." "And what is that?" "Now, he has got five arrows for killing you. You should take and come to Me."
So after fight, they were friends. So Arjuna went to the camp of Duryodhana, and he was well received. "Well, Arjuna, come on. What do you want? Come on. Sit down. Do you want anything from me? If you want, I can stop this fight. I can return you this . . ." Arjuna said: "No. I have not come to you for begging my kingdom. Fighting will go on. But I want . . . you promised something." "Yes. I know. I offer you. What do you want?" "Now, I want those five arrows." At once he delivered.
And this information was carried to, I mean to say, Bhīṣma. Bhīṣma knew that, "Kṛṣṇa is very cunning also. He will save His devotee. So He has done this. All right, in spite of Kṛṣṇa . . . He has broken my promise, and tomorrow I shall see. If Kṛṣṇa does not break His promise, then His friend will be killed. I will fight in such a way."
So he was fighting in such a way that Arjuna became almost dead. Then at that time, Kṛṣṇa . . . the chariot was torn into pieces, and Arjuna fell down. And then Kṛṣṇa took up one of the wheel of the chariot and came before, "Now, Bhīṣma, you stop this fighting; otherwise I will kill you." Bhīṣma at once gave up his arrow, and he offered, "All right. Kill me."
